<br><font size=2 face="sans-serif">As the project was referred to as mpt i used MptElement and MptDocument. I put them into the com.company.mpt package.</font>

<br><font size=2 face="sans-serif">You also have to create your own JDOMFactory (see below) so that the builder returns the correct classes and away you go.</font>
<br>
<br><font size=2 face="sans-serif">Also because I am working with a document with the same tags and attributes all the time I have added many methods to retrieve certain values</font>
<br><font size=2 face="sans-serif">so rather than call getAttributeValue("Weight") i call getWeightAttributeValue() so I can isolate the names of the attributes in one place</font>
<br><font size=2 face="sans-serif">so the maintenance becomes easier. I also created a static build method in MptDocument which uses the correct factory so I can call</font>
<br><font size=2 face="sans-serif">MptDocument.build instead of SAXBuilder.build</font>
<br>
<br><font size=2 face="sans-serif">I have tried some of the parse methods but the problem always seems to come back to knowing how it was stored so you can parse it back, add to that the use of xslt on the stored file and it all gets horribly complicated.</font>

I would agree up to the point you have the float. Is there an accepted way to represent a float which does not have an "." or "," in it.</font><font size=3 face="Times New Roman"> <br>

My biggest problem is that a file created in Europe would have 1.234,00 whereas a uk file would have 1,234.00.

I was wondering if it might be useful to add some methods to Element...<br>
<br>
getInt(java.lang.String name)<br>
<br>
getFloat(java.lang.String name)<br>
<br>
getBoolean(java.lang.String name)<br>
<br>
getString(java.lang.String name)<br>
<br>
etc...<br>
<br>
...that are essentially aliases for...<br>
<br>
getChildTextTrim(java.lang.String name) <br>
<br>
...but with added code that tries to parse the child text string<br>
to the appropriate type...<br>
<br>
<br>
public boolean getBoolean(String name){<br>
boolean result;<br>
try{<br>
result = getChildTextTrim(name).equalsIgnoreCase("true");<br>
}<br>
catch(Exception ex){<br>
result = false;<br>
}<br>
return result;<br>
}<br>
<br>
public String getString(String name){</font>
<br><font size=2 face="Courier New"> String result = getChildTextTrim(name);<br>
if(result == null)<br>
return "";<br>
return result;<br>
}<br>
<br>
public int getInt(String name){<br>
int result;<br>
try{<br>
result = Integer.parseInt(getChildTextTrim(name));<br>
}<br>
catch(Exception ex){<br>
result = 0;<br>
}<br>
return result;<br>
}<br>
<br>
public float getFloat(String name){<br>
float result;<br>
try{<br>
result = Float.parseFloat(getChildTextTrim(name));<br>
}<br>
catch(Exception ex){<br>
result = 0f;<br>
}<br>
return result;<br>
}<br>
<br>
etc...<br>
<br>
<br>
...<br>
